Moistens the Lungs, clears heat, and stops coughs:  for dry Lung or Lung-heat coughs and sore throat.  Especially useful when a chronic cough due to Lung heat has injured the yin.

Clears the Heart and calms the spirit;  for such symptoms as intractable low-grade fever, insomnia, restlessness, and irritability in the aftermath of a febrile disease.  Also for palpitations brought on by insufficiency of qi and yin.
